1 tomcat 日誌詳解

1.1 tomcat 日誌配置檔案

　　tomcat 對應日誌的配置檔案：tomcat目錄下的/conf/logging.properties。

　　tomcat 的日誌等級有：日誌輸出級別：SEVERE (最高級別) > WARNING > INFO > CONFIG > FINE > FINER(精心) > FINEST (所有內容,最低級別)

　　tomcat 有五類日誌：catalina、localhost、manager、admin、host-manager

　　/conf/logging.properties 配置檔案：

 1 #可配置項(5類日誌)：catalina、localhost、manager、admin、host-manager
 2 handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler,
 3 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
 4 
 5 #日誌輸出為輸出到檔案和輸出到控制檯
 
 6 .handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
 7 
 8 #日誌輸出級別：SEVERE (最高級別) > WARNING > INFO > CONFIG > FINE > FINER(精心) > FINEST (所有內容,最低級別)
 9 #配置檔案使catalina日誌輸出級別為FINE

16 #配置檔案使localhost日誌輸出級別為FINE
17 2localhost.org.apache.juli.FileHandler.level = FINE
18 #localhost檔案輸出位置
19 2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
20 #localhost日誌字首為localhost
21 2localhost.org.apache.juli.FileHandler.prefix = localhost.
22 
23 #配置檔案使manager日誌輸出級別為FINE
24 3manager.org.apache.juli.FileHandler.level = FINE
25 #manager檔案輸出位置
26 3manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
27 #manager日誌字首為manager
28 3manager.org.apache.juli.FileHandler.prefix = manager.
29 
30 #配置檔案使host-manager日誌輸出級別為FINE
31 4host-manager.org.apache.juli.FileHandler.level = FINE
32 #host-manager檔案輸出位置
33 4host-manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
34 #host-manager日誌字首為host-manager
35 4host-manager.org.apache.juli.FileHandler.prefix = host-manager.
36 
37 #配置檔案使控制檯日誌輸出級別為FINE
38 java.util.logging.ConsoleHandler.level = FINE
39 #控制檯日誌輸出格式
40 java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
41 
42 #localhost日誌檔案輸出級別為INFO
43 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
44 #localhost日誌檔案輸出處理類2localhost.org.apache.juli.FileHandler
45 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler

1.2 tomcat 日誌檔案詳解

　tomcat 有五類日誌：catalina、localhost、manager、admin、host-manager

　1.2.1 catalina.out ：

catalina.out即標準輸出和標準出錯，所有輸出到這兩個位置的都會進入catalina.out，這裡包含tomcat執行自己輸出的日誌以及應用裡向console輸出的日誌。預設這個日誌檔案是不會進行自動切割的，我們需要藉助其他工具進行切割（注意：catalina.out檔案如果過大會影響）

1.2.2 catalina.YYYY-MM-DD.log

　catalina.{yyyy-MM-dd}.log是tomcat自己執行的一些日誌，這些日誌還會輸出到catalina.out，但是應用向console輸出的日誌不會輸出到catalina.{yyyy-MM-dd}.log,它是tomcat的啟動和暫停時的執行日誌，注意，它和catalina.out是裡面的內容是不一樣的。

　1.2.3 localhost.YYYY-MM-DD.log

　localhost.{yyyy-MM-dd}.log主要是應用初始化(listener, filter, servlet)未處理的異常最後被tomcat捕獲而輸出的日誌,它也是包含tomcat的啟動和暫停時的執行日誌,但它沒有catalina.2018-09-19.log 日誌全。它只是記錄了部分日誌。
